TEMPORARY ACCOUNT-BOOK.

SPECIFICATION forming part of Letters Patent No. 636,662, dated November'7, 1899. Application filed February 23,1899. Serial No- 706,581. (N 0model.)

To all whom it may concern.-

Be it known that I, ROBERT W. HAMILTON, of San Diego, in the county ofSan Diego and State of California, have invented new and usefulImprovements in Temporary Account- Books, of which the following is afull, clear, and exact description.

This invention relates to improvements in books or files for receivingloose account-slips or the like; and the object is to provide a simpleand convenient book of this character in which monthly account-slips maybe loosely placed in alphabetical order, so that they may be readilyfound at the end of a month or other period for the purpose of postingin the ledger.

I will 'describe a temporary account-book embodying my invention andthen point out the novel features in the appended claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the figures.

Figure 1 shows a book embodying my invention in open position. Fig. 2 isan end view of the same folded, and Fig. 3 is a fragmental transversesection of the device.

The book comprises two stiff covers 1 2, connected together by aflexible accordion back 3. Connected to the back 3 by means of flexiblestrips 4 are main leaves 5, upon the outer edges of which primalindex=tabs 6 are attached. The leaves 5 have a considerable spacebetween them at their point of connection with the back 3, so as toprovide accommodation for a large number of accountslips or other papersWithout bulging the bookcovers.

Arranged between adjacent leaves 5 are two or more auxiliary leaves 7.The back edges of sets of leaves 7 are connected together by a flexiblestrip 8, and this strip is connected at convenient points along itscenter to the strip 4 by fastening devices 9. The strip 8 is nearly aswide as the strip 4:, so that the auxiliary leaves may spread apart asthe space between them is filled. The auxiliary leaves at their outeredges are provided with syllabic indexings 10, and it will be noted thatthe leaves 7 are narrower than the main leaves 5, or, in other words,the outer edges of the main leaves extend beyond the outer edges of theauxiliary leaves. By this arrangement when it is desired to open thebook a person may readily insert his fingers between the main leaves,thus making it unnecessary to take hold of and pull upon the tabs 6, asby such methods they might be torn 01f. The auxiliary leaves properlyindexed serve to subdivide the alphabetical index, so that theaccount-slips of difierent persons whose surnames begin with the sameletter can be kept separate as much as possible.

The method of using the book is obvious from its construction, and asthe accountslips are to be filed in proper order immediately aftermaking them it is clear that this book will be of great value to amerchant or bookkeeper.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. A temporary account-book comprising covers, aflexible accordion back connecting said covers, main leaves spacedapart, a flexible strip connecting adjacent main leaves at the rear edgeto each other and to the flexible back, auxiliary leaves arrangedbetween adjacent main leaves, a strip of flexible material connectingthe rear edges of the auxiliary leaves, and having a width substantiallyequal to that of the first-named strip, so that the auxiliary leaves mayspread apart as the space between them is filled, the two strips beingconnected together at convenient points along the center, substantiallyas specified.

2. A temporary account-book, comprising main leaves, spaced apart andconnected at their back edges by flexible expanding connections,auxiliary leaves narrower than the main leaves and arranged betweenadjacent main leaves, the said auxiliary leaves being connected at theback edges, with each other and with the flexible connections for themain leaves, and index-tabs on the main leaves, substantially asspecified.

3. A temporary account-book, comprising covers, a flexible accordionback connecting said covers, main leaves spaced apart, wide flexiblestrips connecting adjacent main leaves to each other and to the back,auxiliary leaves arranged between adjacent main leaves and narrower thanthe main leaves, flexible strips connecting together the back edges ofthe auxiliary leaves, the said strips being nearly as wide as the stripconnecting the main leaves, so that the auxiliary leaves may spreadapart as the space between them is filled, and means for fastening thestrips connecting the auxiliary leaves, to the strips connecting themain leaves at points along the center,-the said main leaves andauxiliary 10 leaves being suitably indexed, substantially as specified.

ROBERT W. HAMILTON.
